• Industrial Power Supply
• Motor & Compressor
• IT / SMT Production Line
• Renewable Energy
• Electric Vehicles
• Transportation

• CE & RoHS certificated.

• Modularized inverter which is compact, smaller, high power density and easy to maintain.

• 7-inch touch screen which can display the phase voltage, current, frequency, active/apparent power, power factor and test information.

• Ability to simulate abnormal power status: STEP and GRADUAL change modes allow users to set sequences of start/end voltage, frequency and running time with ease.

• Comprehensive protections which include output undervoltage / overvoltage, overcurrent, overload, input undervoltage / overvoltage, overheat and other more than twenty fault conditions.

• Three-phase voltage independently adjustable function: each phase voltage can be adjusted independently; therefore AFV can power more than one single-phase loads.

• Phase angle adjustment function: can adjust the phase angle between each phase (for three phase system).

Preen's AFV series is a programmable AC power source that can be remotely controlled and integrated with other systems for automatic testing. AFV series delivers precise output voltage and frequency to meet a wide range of industrial requirements. For users in home appliances, electronics, medical equipment, and lighting this variable AC supply lets you simulate standard or abnormal power conditions quickly and accurately.

AFV builds-in standard programmable features, such as STEP and GRADUAL features, which are ideal for laboratories, certification and R&D institution’s compliance test.

The user friendly touch screen supports user to operate AFV series intuitive and easily, and the user can remote control the unit via the standard RS-485 or RS232 (Optional for Ethernet, GPIB) interface. The Programmable AC source is coupled with output voltage range of 0~300V and output frequency of standard 45~65Hz or optional 45~500Hz. Moreover, the AFV series provides complete product protection, such as OVP, UVP, OCP, OPP, OTP and short circuit protection.

AFV with 7-inch touch screen of intuitive operation, easy to operate, quick setting, easy to use. Through the remote control interface (RS-485 / RS-232 / GPIB / Ethernet), users can set the desired output parameters and monitor the output value.

AFV series has the STEP change mode which provides up to 24 sequences and up to 255 cycles. The output voltage, frequency, and running time in each sequence can be set on the touch screen. These functions are widely used in the performance test of electric motor or home appliance load.

AFV series has the GRADUAL change mode which provides up to 12 sequences and up to 255 cycles. Through this feature, users are allowed to set the product output, such as start/end output voltage, start/end output frequency and dwell time of performing the GRADUAL feature in each of the adjustable sets, and then the product output will change according to the setting slew rate.

Soft-start function can effectively reduce the starting current of motor load or inductive load. The users have more flexibility on selection of power capacity and more efficiency on space usage. They can purchase more cost-effective products.

Users are allowed to control three-phase output voltage independently. The product can be used as one unit of three-phase power supply or as three units of single-phase power supply.

With its high reliability, capability of complex power line simulation and high output power, the AFV series has been widely applied for applications on home appliance, electric vehicle charger, motor, electronics and medical equipment. It is a AC power source suitable from R&D verification to mass production testing.
